degraded RAID 1+0 in ML30 G9 with 4-8TB in RAID 1+0 using b140i

[sammy mah_1]

I got a message in ILO of a failed hard drive in bay3 of my ML30g9 with b140i RAID controller.  Drives are 4x8TB Seagate Ironwolf drives, and one has failed in bay3, and the array is degraded.

How do I replace the drive? Do I have to power down the system? 

What happens after replacement and power on? Will it automatically recognize the replacement drive (8TB, 7200rpm drive) and begin rebuid of array?

Is there something I have to do in F2?  

The documentation was unclear of the process of what happens..

or is this hot swappable? The drives are not in an HP carrier, I believe they are connected with a SATA connector to the B140i controller board.

How do I replace the drive? Hot Swap

Do I have to power down the system?  Not Mandatory

What happens after replacement and power on? Rebuild the array but better to hot swap 

Will it automatically recognize the replacement drive (8TB, 7200rpm drive) and begin rebuid of array? Yes 

Is there something I have to do in F2?   No need

After replaced the drive it will take time to rebuild, be patience.
